I'm sorry, I still don't understand. You said he's not a "real catcher." The statistics and general opinion show that not only is he a "real catcher," but he is one of baseball's best. He won the AL catching Gold Glove last year.
Here is but one alternative source:
Ranks him 3rd in 2012, after being 1st last year.
You then say he's "too tall" and provide as evidence..........
...a single passed ball.
Here's what the statistics say, according to the above-named source:
Pitch Blocking (Passed Balls and Wild Pitches):
Matt Wieters’ bat may have calmed down, but he led the way in pitch-blocking again. I had Wieters as the best-fielding catcher in baseball last year, and he’s established himself as perhaps the best in the American League, although Salvador Perez might claim that by next year. Ryan Hanigan of the Reds also did well here, despite not being heralded for his defensive abilities.
On throwing people out:
No real surprises here. Yadier Molina takes it (can’t believe how often teams try to run on him), followed by Hanigan, Matt Wieters, and the underrated Miguel Montero. Special mention to David Ross, who saved the Atlanta Bravse just over four runs in this category despite starting less than fifty games. Dude is good defensively, and has been an above-average hitter the last four years. I don’t get why other teams don’t try to sign him as a starter.
I'm not sure what else to say. It was a wonky play at home, and Wieters should have done better, but to say he's not a "real catcher" or that he's somehow "too tall" for the position is obviously nonsense.
Just the night before, he made an incredible pick on a bad throw to nail a guy at the plate that most catchers would never have made.
